英格兰vs伊朗让球RStudioWorkbench、启动器和Kubernetes正常运行时,Kubernetes工人节点应能够拉出docker图像,从dockerhub或docker注册程序调出启动程序会议使用,或按kubernetes配置
故障解析步能帮助你判断dock图像是否正确配置库贝涅斯剖面配置并判定Kubernetes工人节点拥有从dockerHub或docker注册所拉出Docker图像所需的网络访问权限
故障解析步骤##
启动器和库贝内特斯应用测试功能英格兰vs伊朗让球rstudio/r-session-completedocker图像文档引用英格兰vs伊朗让球studioWorkbenche集成库贝涅茨.即便你计划使用自定义Docker图像启动器,你仍应先测试启动器功能英格兰vs伊朗让球rstudio/r-session-completeDocker图像
验证你配置中正确 docker图像使用库贝涅斯剖面配置文件内应写相似线 :
英格兰vs伊朗让球File: /etc/rstudio/launcher.kubernetes.profiles.conf
container-images=英格兰vs伊朗让球rstudio/r-session-complete:centos7-2022.07.2-576.pro12default-container-image=英格兰vs伊朗让球rstudio/r-session-complete:centos7-2022.07.2-576.pro12信息学
英格兰vs伊朗让球保证库贝涅斯配置文件中的docker图像版本与你安装的RStudioWorkbench版本匹配
验证您能从dockerHub调出默认docker图像,从Kubernetes工人节点或服务器运行下命令,服务器组与Kubernetes工人节点相同:
终端
英格兰vs伊朗让球$ docker pull rstudio/r-session-complete:centos7-2022.07.2-576.pro12信息学
使用从dockerhub预设图像需要库贝涅斯工人节点访问dockerhub测试
如果在受限网络环境内无法实现,则需要遵循离线环境使用docker图像卡塔尔世界杯欧洲预选赛赛程表段支持文章英格兰vs伊朗让球Docker图像使用RSTUDIOWORBENCH、启动器和Kubernetes.
恢复服务测试##
英格兰vs伊朗让球验证Docker图像正确配置并检查DockerHub连接或docker注册后,重新启动RstudioWorkbench服务
终端
英格兰vs伊朗让球sudo Rstudio-server重开英格兰vs伊朗让球验证服务运行并尝试从RStudioWorkbench主页启动新片段
验证库贝涅斯工人能拉出dockerHub图像或将图像存入docker注册系统,但在启动新会话时仍然出错时,则继续处理
步骤13-验证Kubernetes工人节点.
